Razor or React?

I would like to do a small pet project - a website. In the backend I will use ASP.NET, but in the frontend I am a complete zero. I would like to be able to show this project as a portfolio of work for the backend. Plus to understand how the frontend connects with the backend, at least on a minimal level. But I don't know what is better to use for frontend Razor Pages or React....

✅ What is a primary constructor in C#

Hello guys, was just reading a bit about primary constructors. My question is, primary constructors is just a "fancy" way to write less code instead of declaring a whole constructor? Or are there any reasons why we would use primary constructors?

Application Insights OpenTelemetry fresh install not showing stack trace

I just installed Application Insights OpenTelemtery into a fresh copy of IdentityServer 7. I'm getting a 500 error on login. The error.type field shows System.InvalidOperationException, but no stack trace is shown. Identity Server 7 comes with SeriLog installed by default. I'm not sure if that's somehow intercepting something but it seems as though if it can get the error.type, it should be able to get the stack trace. Normally I see here a checkbox Just My Code, and when I uncheck that, I see the full stack trace....

✅ Event Handler functionality

Hi, I have an assignment where I need to create a list of rooms, each represented as a unique object. When a user clicks on a room, they should be able to press a button to request a booking for that specific room. However, I'm unsure how to use the selected room's object to transfer its details to another page, where the user can continue adding booking information. Any guidance would be appreciated!

Planning an app out before starting

I want to make a gong fu cha (tea brewing style, the main thing is that it involves even up to 10 steeps, first ones are short and they're getting progressively longer) timer & steep counter app with a statistics tab. The timer should allow to set a base steep time and an increment to be added each round. The app should allow to see how many brewing sessions there were each month. Each session should have the tea's name in it and a space for flavor and scent description. I'll be using AvaloniaUI and focus on mobile. I guess I'm going to need some sort of database for the descriptions and saving the sessions, I worked with entity framework and postgresql before. I want to give test driven development a try, seems like a good thing to know, although I don't know if I'll be able to do it before determining the app's structure down to each function and accurately tell what needs testing and what doesn't. Did I miss anything important?...

Serializing a Function in Unity using AnimationCurve

Hey there guys, I'm working on a game with Unity right now and I have a few classes which basically represent certain types of functions that I want to use in some contexts. What i would like to know is if there is a way to translate my functions into animation curves (ideally using a custom attribute such as SerializeCurveAttribute) so that I can use Unity's built-in serialization for said curves. I'm not quite sure how to go about this, as I've barely written any attributes, and the decompiled code for Unity's SerializeField literally contains nothing. Here is the code for my curve classes: ```cs public interface ICurve...
